This model generates design storms for a given storm type, duration, and depth that the user can enter from a simple dashboard. The design storms are all derived from standard SCS 24-hr design storm distributions for 0.1 hour time intervals. If a duration smaller than 24 hours is selected, then GoldSim will transform the distribution into the smaller time frame. Submodels are used to process the 24-hr storm time series to determine variables that are used to prepare the transformed time series output. The result is a storm distribution that is specific to the duration and type specified. As a final step, the storm depth is applied to this distribution to generate the actual precipitation rates through time.
